The bill introduces a new section to chapter 36.01 RCW, establishing reporting requirements for counties regarding public works activities. Counties are mandated to collect and retain records of any public works activity they undertake, which must include specific details such as the amount of natural or organic material removed, the disposal locations of these materials, whether any were reused for other projects, and if they were tested for contaminants along with the results of those tests.

Additionally, the bill defines key terms relevant to the reporting requirements. "De minimis amount" is specified as a quantity of material that is too small to be easily noticed without detailed examination, while "public works activity" refers to maintenance or construction activities conducted by the county on roads adjacent to properties owned by others. This legislation aims to enhance transparency and accountability in county public works projects by ensuring comprehensive documentation of environmental impacts.
